Here’s a description of the event by photographer Steph Goralnick who was in attendance:

Quite possibly the ballsiest interpretation of the “popup restaurant” phenomenon to date: 12 guests were treated to a full 6 courses on an NYC subway commute from 8th Avenue to Canarsie, with a new dish being served every third stop. Courses were plated by teams either on the platform, or in the train itself, and served to guests on custom-built straphanger tables. The exquisitely planned and executed event went off (amazingly) without a hitch. The Great Gatsby was read, diners were stuffed, onlookers drooled.
